I managed to d/l GPL code for v1.1.03 from Linksys and built fw image that works, e.g. I u/l it to my wrvs last night, and rebooted into it. Everything work as before, routing, firewalling and wifi…. phew! 🙂

Next is to adding features/functionalities. More to follow.

I found link to the 1.1.13 src, compiled and have been running that for last week or so. So far so good….

How to fix corrupted elasticsearch translog.

In 5.0 there is a tool which can be used to truncate corrupt translog files. This doesn't exist in 2.x but there is a workaround:
POST my_index/_close
PUT my_index/_settings
{ "index.engine.force_new_translog": true }
POST my_index/_open
PUT my_index/_settings
{ "index.engine.force_new_translog": false }
NOTE: Any data in the corrupted translog will be lost.

How to size a cluster?

I want to create a new Elasticsearch cluster. What are the recommended sizing guidelines?
Answer:
This is very much a use case dependent answer. The factors that should be taken into considerations are:

Frequency of new data. How often is new data to be indexed? Daily? Hourly?
